Hi, I'm Mo'.

I'm Mo' Claudius, a full-stack engineer with 9+ years of experience. I build with Angular, React, Ruby on Rails, Node.js, and NestJS, and most of my thinking goes to architecture and performance: event-driven and domain-driven design, optimization, and how the pieces fit and run.

Twice a week, I publish what I'm learning here. The throughline is always the same: where should the boundary sit, what does an abstraction cost, and what breaks when you get it wrong. Every post is written so you can follow along.
